Long Answer Question


Que – What is germination? What are the conditions required for germination?

Germination is the process of converting seeds into new plants. Once seeds are sown, they require a specific environment for growth. Water, air, soil, and temperature all influence how deep the seed is planted. As soon as all these conditions are met, the seed germinates into a baby plant with the help of the stored food in the seeds. When a seed takes in water, it activates its enzymes. By using these enzymes, stored food becomes soluble and moves into radicles and plumules for growth.


Que – Self-Pollination, and Cross-Pollination

This occurs between the flowers of the same plant. It does not require any pollination agents. This involves the maturation of pollen and eggs at the same time.

It occurs between the flowers of plants of the same variety. Pollination is carried out by air, water, etc. It is not necessary for pollen and eggs to mature simultaneously.
